Description

Die Erfindung betrifft eine Vorrichtung zur Längsverschiebung der Lichtleitermäntel (4, 5) eines Lichtleiters (1) für die Verbindung eines medizinischen Lasergeräts mit einem Endoskop, wobei der Lichtleiter (1) an dem Ende, an welches das Endoskop anschließbar ist, eine Vorrichtung (2) zur Längsverschiebung des Lichtleiters (1) aufweist.The invention relates to a device for longitudinally displacing the light guide cladding (4, 5) of a light guide (1) for connecting a medical laser device to an endoscope, the light guide (1) at the end to which the endoscope can be connected, a device ( 2 ) for longitudinal displacement of the light guide (1).

Ein derartiger Lichtleiter ist in der DE-PS 29 45 080 beschrieben. Der Lichtleiter weist hierbei am Anschlußstück zum Endoskop eine Vorrichtung zur Längsverschiebung des Lichtleiters auf, die es ermöglicht, das distale Ende des Lichtleiters um einige Millimeter zwangsläufig reversibel aus dem Endoskop austreten zu lassen, um die Lichtleiterspitze während einer Behandlung reinigen zu können. Eine Längenänderung des austretenden Lichtleiters um eine Strecke von bis zu einem Meter ist jedoch mit dieser Vorrichtung nicht möglich.Such a light guide is described in DE-PS 29 45 080. The light guide has a device for longitudinally displacing the light guide on the connection piece to the endoscope, which makes it possible for the distal end of the light guide to exit the endoscope in a reversible manner by a few millimeters in order to be able to clean the tip of the light guide during a treatment. A change in length of the emerging light guide by a distance of up to one meter is not possible with this device.

Aus der DE-OS 21 45 921 ist ein Lichtleiter bekannt geworden, bei dem die Lichtleitfaser in einem Tubus angeordnet ist, der bezüglich eines weiteren Tubus teleskopartig reversibel verschiebbar gelagert ist. Eine Längenverstellung des Lichtleiters ist jedoch nicht vorgesehen.From DE-OS 21 45 921 an optical fiber has become known, in which the optical fiber is arranged in a tube, which is mounted so that it can be reversibly displaced telescopically with respect to another tube. A length adjustment of the light guide is not provided.

Der Erfindung liegt deshalb die Aufgabe zugrunde, eine Lichtleiterverbindung zwischen einem medizinischen Lasergerät und einem Endoskop so zu gestalten, daß der aus dem Anschlußstück zum Endoskop austretende Lichtleiter auf beliebige Längen bis zu einem Meter einstellbar ist, so daß der Lichtleiter an verschiedene Endoskope angepaßt werden kann, und daß die bekannte Vorrichtung zur Längsverschiebung des Lichtleiters weiterhin ihre Funktion erfüllen kann.The invention is therefore based on the object of designing a light guide connection between a medical laser device and an endoscope so that the light guide emerging from the connection piece to the endoscope can be adjusted to any length up to one meter, so that the light guide can be adapted to different endoscopes , and that the known device for longitudinal displacement of the light guide can continue to perform its function.

Diese Aufgabe wird erfindungsgemäß durch die im kennzeichnenden Teil des Patentanspruches wiedergegebenen Merkmale gelöst.This object is achieved by the features set out in the characterizing part of the patent claim.

Der besondere Vorteil der Vorrichtung ist es, daß für jedes auf dem Markt befindliche Endoskop mit passendem Anschluß jede beliebige Länge des aus dem Anschlußstück austretenden Lichtleiters einstellbar ist, so daß sich dadurch die Lagerhaltung für Lichtleiter drastisch reduzieren läßt. Außerdem kann ein Lichtleiter über längere Zeit durch einfaches Abschneiden seiner distalen Spitze immer wieder benutzt werden, während bisher im Falle einer Beschädigung jeweils der gesamte Lichtleiter ausgetauscht werden mußte. Weiterhin ergibt sich durch den steifen Lichtleitermantel ein guter Knickschutz und eine Zugentlastung für den Lichtleiter.The particular advantage of the device is that any length of the light guide emerging from the connector can be set for each endoscope on the market with a suitable connection, so that this can drastically reduce the storage for fiber optics. In addition, a light guide can be used over and over again by simply cutting off its distal tip, whereas previously the entire light guide had to be replaced in the event of damage. Furthermore, it results from the stiff Light guide jacket a good kink protection and a strain relief for the light guide.

Ein Ausführungsbeispiel der Erfindung ist nachfolgend anhand der Zeichnung beschrieben. Die einzige Figur der Zeichnung zeigt schematisch vereinfacht den Aufbau des erfindungsgemäß in der Länge einstellbaren Lichtleiters.An embodiment of the invention is described below with reference to the drawing. The single figure of the drawing shows schematically simplified the structure of the light guide adjustable in length according to the invention.

Im Anschlußstück 3 zum nicht dargestellten medizinischen Lasergerät sind der Lichtleiter 1 und der Lichtleitermantel 5 befestigt. In den größeren Lichtleitermantel 5, der den Innendurchmesser di aufweist, ist an der Übergangsstelle 6 der kleinere Lichtleitermantel 4, der den Außendurchmesser da < di aufweist, eingeschoben. Beide Lichtleitermäntel bestehen aus biegesteifem Material, beispielsweise aus einer mit Kunststoff überzogenen Metallspirale. Innerhalb der Lichtleitermäntel ist der Lichtleiter 1 lose gelagert.In the connector 3 to the medical laser device, not shown, the light guide 1 and the light guide jacket 5 are attached. In the larger light guide jacket 5, which has the inner diameter d i , the smaller light guide jacket 4, which has the outer diameter d a <d i , is inserted at the transition point 6. Both fiber optic jackets are made of rigid material, for example a plastic spiral covered with plastic. The light guide 1 is loosely mounted within the light guide jacket.

Die Verklemmung der beiden Lichtleitermäntel 4, 5 gegeneinander erfolgt mittels der ersten lösbaren Klemmverbindung 7a, ... 7e. Der größere Lichtleitermantel 5 ist auf eine Kunststoffhülse 7e geschoben und mit dieser verklebt. Die Klemmung wird durch zwei Klemmhülsen 7a, 7b aus Kunststoff vollzogen, die mittels einer konischen Trennfläche 9 aneinander anliegen. Die im Konusbereich innenliegende Hülse 7a kann geschlitzt ausgeführt sein. Die Klemmung tritt ein, wenn die beiden Metallhülsen 7c, 7d, die die Kunststoffhülse 7e und die Klemmhülsen 7a, 7b umfassen, gegeneinander verschraubt werden, so daß die beiden Klemmhülsen 7a, 7b in axialer Richtung aufeinander geschoben werden.The two light guide sleeves 4, 5 are clamped against one another by means of the first releasable clamping connection 7a,... 7e. The larger light guide jacket 5 is pushed onto a plastic sleeve 7e and glued to it. The clamping is carried out by two clamping sleeves 7a, 7b made of plastic, which abut one another by means of a conical separating surface 9. The inner sleeve 7a in the cone area can be slotted. The clamping occurs when the two metal sleeves 7c, 7d, which comprise the plastic sleeve 7e and the clamping sleeves 7a, 7b, are screwed together, so that the two clamping sleeves 7a, 7b are pushed onto one another in the axial direction.

Die weitere lösbare Klemmverbindung an der Vorrichtung zur Längsverschiebung des Lichtleiters 2, die aus den Teilen 8a, ..., 8c besteht, ist prinzipiell gleichartig wie die erste lösbare Klemmverbindung 7a, ..., 7e aufgebaut und verbindet den Lichtleiter 1 mit dem kleineren Lichtleitermantel 4.The further releasable clamp connection on the device for longitudinal displacement of the light guide 2 , which consists of the parts 8a, ..., 8c, is basically constructed in the same way as the first releasable clamp connection 7a, ..., 7e and connects the light guide 1 to the smaller one Light guide jacket 4.

Mit Hilfe der vorbeschriebenen Vorrichtung kann nun leicht die Länge X des aus der Vorrichtung zur Längsverschiebung 2 austretenden Lichtleiters 1a innerhalb der durch die Länge des kleineren und des größeren Lichtleitermantels 4, 5 vorgegebenen Bereichs eingestellt werden. Hierzu wird zunächt die Klemmung an der Vorrichtung zur Längsverschiebung 2 und dann die Klemmung an der übergangsstelle 6 gelöst. Nach der erfolgten Einstellung der Länge X erfolgt die Klemmung in der umgekehrten Reihenfolge.With the help of the device described above, the length X can now easily of the light guide 1 a emerging from the device for longitudinal displacement 2 can be set within the range predetermined by the length of the smaller and the larger light guide jacket 4, 5. For this purpose, first the clamping on the device for longitudinal displacement 2 and then the clamping on the transition point 6 is released. After the length X has been set, the clamping takes place in the reverse order.
